Description

Technical Field

[0001] This utility model relates to the field of lock processing technology, specifically to a device for processing drilled pin holes in locks. Background Technology

[0002] The lock pin hole is an important component of a lock, playing a key role in its functionality and security. Lock pin holes are typically located between the lock cylinder and the lock body, or at the mating point between the bolt and the latch. A device specifically designed for machining lock pin holes improves machining accuracy and efficiency, ensuring the quality and security of the lock.

[0003] However, existing technologies still have the following problems:

[0004] First, during processing, the lock needs to be drilled to create pin holes that mate with the lock cylinder and lock body. However, the existing pin-drilling devices on the market are not convenient for accurately drilling pin holes in locks, making them less practical.

[0005] Secondly, the lock may shift during the manufacturing process, requiring a fit to the shape of the lock for better clamping and fixing. However, existing technology is not convenient for applying clamping force evenly to the lock from multiple directions, resulting in low clamping stability.

[0006] To address the aforementioned problems, the inventors have proposed a device for machining drilled pin holes in locks. Utility Model Content

One end of the second rotating shaft 308 is rotatably connected to one side of the inner wall of the housing 302. A first connecting rod 309 is fixedly connected to one end of the second sprocket 307. One end of the first connecting rod 309 is rotatably connected to the connecting plate 310. The first sprocket 305 drives the second sprocket 307 to rotate via the chain belt 306. The second sprocket 307 drives the second rotating shaft 308 to rotate. The second sprocket 307 also drives the first connecting rod 309 to rotate. The first connecting rod 309 drives the connecting plate 310 to move. The lower part of one end of the connecting plate 310 is rotatably connected to the second connecting rod 311. One end of the second connecting rod 311 is fixedly connected to the box body 312. The outer surface of the box body 312 is movably connected to the bottom end of the shell 302. Both ends of the box 312 are fixedly connected to the upper part of the sliding rods 313. The opposite ends of the sliding rods 313 are fixedly connected to the limit rods 314. Both ends of the box 312 are provided with first sliding grooves 315. The opposite ends of the brackets 301 are provided with second sliding grooves 316. The outer surface of the sliding rods 313 is in contact with the inner wall of the first sliding groove 315 and the second sliding groove 316. The lower inner wall of the box 312 is fixedly connected to the second motor 317. The output end of the second motor 317 passes through the bottom end of the box 312 and is fixedly connected to the drill bit 318.

[0020] The output of the second motor 317 drives the drill bit 318 to rotate at high speed. The rotating drill bit 318 drills pin holes in the lock fixed by the clamping device 2, which facilitates precise drilling of pin holes in the lock.

[0021] The clamping device 2 includes a base 21, the bottom end of which is fixedly connected to the top end of the base plate 1. A placement plate 22 is rotatably connected to the middle of the top end of the base 21. A plurality of clamping plates 23 arranged in a circular array are fixedly connected to the top end of the base 21. A clamping plate 24 is movably connected to one end of each clamping plate 23. The inner wall of the clamping plate 23 is in contact with the outer surface of the clamping plate 24. A limit plate 29 is fixedly connected to one end of each clamping plate 24. One end of each clamping plate 24 is arc-shaped. The rotation of the threaded rod 26 will cause it to move in the horizontal direction. The movement of the threaded rod 26 drives the clamping plate 24 to move in the horizontal direction. One of the clamping plates 24 moves, and this clamping plate 24 is connected to other clamping plates 24 through the third connecting rod 28, so that all clamping plates 24 move synchronously. The top of the base plate 1 is fixedly connected to the connecting block 25. One end of one of the clamping plates 24 is rotatably connected to the threaded rod 26. The outer surface of the threaded rod 26 is threadedly connected to one end of the connecting block 25. One end of the threaded rod 26 is fixedly connected to the rotating rod 27. The top of the placement plate 22 is rotatably connected to multiple third connecting rods 28 arranged in a ring array. The top of the third connecting rod 28 is rotatably connected to the bottom end of the clamping plate 24.

[0022] One end of each of the multiple clamping plates 24 is arc-shaped. They gradually approach the lock and eventually clamp and fix the lock on the placement plate 22, so as to apply clamping force to the lock evenly from multiple directions.

[0023] Working principle: The lock is placed on the placement plate 22. Rotating the rotating rod 27 drives the threaded rod 26 to rotate. Since the threaded rod 26 is threadedly connected to the connecting block 25, the rotation of the threaded rod 26 will cause it to move in the horizontal direction. The movement of the threaded rod 26 drives a clamping plate 24 connected to it to move. This clamping plate 24 is connected to other clamping plates 24 through the third connecting rod 28, so that all clamping plates 24 move synchronously. The clamping plates 24 move along a specific direction under the restriction of the clamping plate 23. One end of multiple clamping plates 24 is arc-shaped. They gradually approach the lock and finally clamp and fix the lock on the placement plate 22, thereby achieving the purpose of applying clamping force to the lock evenly from multiple directions.

[0024] When the first motor 304 is started, its output drives the first rotating shaft 303 to rotate. The first sprocket 305, fixedly sleeved on the first rotating shaft 303, rotates accordingly. The first sprocket 305 drives the second sprocket 307 to rotate via the chain belt 306. The second sprocket 307 drives the second rotating shaft 308 to rotate. The second sprocket 307 also drives the first connecting rod 309 to rotate. The first connecting rod 309 drives the connecting plate 310 to move, and the connecting plate 310 drives the second connecting rod 311 to move up and down. The second connecting rod 311 is connected to the housing 312. This causes the box 312 to move up and down. The slide rods 313 at both ends of the box 312 slide within the first slide groove 315 and the second slide groove 316. The limiting rods 314 on the slide rods 313 prevent the box 312 from sliding out excessively. When the box 312 moves down to the appropriate position, the second motor 317 on the lower inner wall of the box 312 is activated. The output end of the second motor 317 drives the drill bit 318 to rotate at high speed. The rotating drill bit 318 drills pin holes in the lock fixed by the clamping device 2, thereby achieving the purpose of facilitating precise drilling of pin holes in the lock.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
